Robinson is in his eighth NFL season, having spent four years in San Francisco before coming to Seattle in 2010. He is viewed as an excellent blocker who helped Marshawn Lynch to back-to-back 1,000-yard seasons, including a career-best 1,590 yards in 2012.

But the Seahawks have two young fullbacks they like: rookie Spencer Ware and second-year player Derrick Coleman. Robinson was scheduled to make $2.5 million this season.

Robinson did not play in the final two preseason games because he was suffering from a virus. He was extremely popular with the Seahawks players and grew to become one of the leaders for a young and blossoming group of players that includes quarterback Russell Wilson and middle linebacker Bobby Wagner, who reacted on Twitter:

I'm going to miss you @RealMikeRob You're the best in the business. Love you VA.
